RUDOLF KRON, OF GOLZERN, GERMANY.

PROCESS OF PRODUCING YARN FROM MAGAZINE-ROLLS OF SHORT-FIBER MATERIAL IN A MOIST CONDITION.

SPECIFICATION forming part of Letters Patent No. 776,474, dated November 29, 1904.

Original application filed December 6, 1902, Serial No. 134,201. Divided and this application filed May 22, 1903. Serial No. 158,260. (No specimens.)

To all whom it may concern:

Be it known that I, RUDOLF KRON, a citizen of the Republic of Switzerland, and a resident of Golzern, in the Kingdom of Saxony, in the German Empire, have invented new and useful Improvements in Processes for the Production of Yarn from Magazine -Rolls of Short-Fiber Material in a Moist Condition, of which the following is a specification, reference being had to the accompanying drawings, designed to show the magazine-roll employed in producing the desired result.

The present invention, which has been de scribed in my application, Serial No. 134,201, filed December 6, 1902, of which the present application is a division, has for its object a process for the production of yarn from magazine-rolls of short-fiber material in a moist condition; and it consists, first, in drawing off separate one or more strips from a web composed of short-fiber materialas paper pulp, cellulose, asbestos, silk, and the like provided in a longitudinal direction with furrows a suitable distance apart and rolled up in a moist condition, and, second, in twisting said strips in a moist condition on a spinning,

spooling, or twisting machine, one such strip being twisted singly or two or more being twisted together. For the purpose of producing yarn from magazine-rolls the endless web of paper-pulp being still in a moist condition is provided by suitable means and before its rolling up with longitudinal furrows a suitable distance apart. The rolling off from the magazine-roll takes place in the form of separate small strips by dividing the web along the longitudinal furrows formed in such web. This rolling or drawing off of small strips from the magazine-roll is possible only if the web of paper-pulp is still in a moist condition. The Web rolled up in a moist condition maintains or insures a sufficient moisture during weeks and months, so that magazine-rolls can be kept in stock.

For supplying the spinning, spooling, or twisting machines with the magazine-rolls produced according to the process described above the rolls of a considerable width are divided, by means of cutting, sawing, and other mechanical means, in sections, and these sections of the original roll are placed in a vertical, horizontal, or inclined position in front of the machine.

Figures 1 and 2 of the annexed drawings show in side view a section of a divided magazine-roll composed of a plurality of separate strips or strips divided by furrows, but adhering still together by a thin film. Such a section of a magazine-roll can be placed horizontally, and the single strips supplied to the spinning, spooling, or twisting machine can be drawn ofi from the periphery of the magazine-roll, as shown in Fig. 1, or from the inner surface of the roll mentioned, as shown in Fig. 2, which shows part of the roll in section. Two or more of the sections of a magazine-roll can also be placed in front of the spinning, spooling, or twisting machine in a vertical position, as shown in Figs. 3 and L, Fig. 3 showing in front view part of a twisting-machine, and Fig. 4 a plan of same.

a a are two sections of a magazine-roll placed on a core 7). The strips of the roll, still adhering together by a thin and narrow film, are drawn off from the rolls, as shown, and guided to the stationary guide-pins 0, set to change the course of the strips (Z, and spread them in lines diverging toward the rollers a. The strips (Z are thereafter guided to fliers g and bobbins j, which maybe of similar construc tion to those in general use for spinning. By these fliers the strips d may be twisted singly, as illustrated at the left of Fig. 3, or two or more together, as illustrated at the right of the same figure.

\Nhat I claim as my invention is The process herein described for the manufacturing of yarn from magazine rolls of short-fiber material in a moist condition, said process consisting in rolling off separateone or more-strips from an endless web consistiug of the short-fiber material furrowed in my invention I have signed my name, in presthe direction of its length at suitable interence of two witnesses, this 4th day of May,
